Split into multiple files (angular-fx-roll.js, angular-fx-fade.js etc...)

Maybe better to serve also sub files to choose animations we want to use

The main file is likely angular-fx.js or a similar bundled script. Examine the source to understand how animation directives (ngfx-bounce, ngfx-shake, etc.) are currently organized. The goal is to split them into separate files like angular-fx-roll.js, angular-fx-fade.js. Check the build process to see how these files are served or bundled. A newcomer would need to understand the AngularJS directive structure and the project's module system.
